Application filed September 1, M21.

VTo all whom t may concern:

Be it known that l, wir Gnesren, citizen or Canada, residing atV Cupar,in the District ot Humboldt and Province or" Saskatchewan Canada, hai/einvented certa-in new and useful impr venients in Cable andTelephone-Tine Containing Rails, of which the following isspecilication.

This invention relates to railroad telephone system whereby telephcningmay be ldone from inov'ng trains and it has for an object to p siinpleystein for this purpose which may also be used by station agents alongthe railroad.

For further comprehension ot the invention, et the objects andadvantages l, thereof, reference will be had to the followingdescription and accompanying drawings, and to the appended claims inwhich the various novel features of the invention are more particularlyset forth.

Figure 1 oi the drawings is a transverse sectional view showing a trackrail and its support with the invention applied thereto.

Fig. 2 is a similar view but taken at a different point.

F ig. 3 is a transverse sectional view illustrating the manner of"connecting the stations along the line to the system.

Fig. 4. is al plan view oit a portionof a railroad track having theinvention applied thereto.

Fig. 5 is a side elevation of a portion or'1 the track, indicating partoi a railroad train in position thereon.

In the drawings the reference numeral 10 indicates a pair of trackrails, and 11 the ties on which the rails rest'. Each of these rails hasa thickened web formed partly by an integral member 10 and partly by asupplementary member 12 having a dove-tail tongue and groove connection18 with the member 10.

The web member' 10 presents a longitudinal recess on its inner tacewhich recess is closed on its fourth side by the tongue of member 12.This recess serves as a conduit .tor a series or wires. indicated atThese wires 15 connected to difierent sections ott a contact rail 17 setin, and ei;- tending along, an insulating base element 18 on the rail,this insulating base element being here shown as connected to the railby a tongue and groove connection 19, while the rail has a tongue andgroei-fe connection 17 with the element 18.

Serial No. 497,547.

To eliiect the electrical connections between the wires and the varioussections or contact rail l'r, the ends of the wires are tened by screwssuch as 20 to blocks 21 1f The underside of each block is en Ted by astud 22 having a cupped enent 23 on its lower end engaged in a suitablerecess in the tie 11, the studs 22 being' pressed upward against theblocks 21 by coiled expansion spring 24. A similar wing a cuppedenlargement 31 on s lower end is pressed by a spring 32 against ieunderside oi each section ci the contact Contact is maintained betweenthe members end 31 by ineans of a bar 33 having semi-circular ends Silwhich engage the sides ot said members. To secure these parts inr placesuitable recesses are formed in the bottom oit the ties 11 and areclosed byV iiller locks 35 held in place by screws 36. llheseiillerblocks serve as abutments ici' the springs 2d and 32. The wires 15,blocks 21, screws 2O and studs 22 are insulated from the rail 10 byinsulating lining indicated at 37.

rihcse rails are adapted to be engaged by vh els 40 on the lower ends ofspring ressed trolley poles 41, ont ordinary con- -truction throughwhich passes lead wires o telephones, indicated at i-S, which may be oaced in various parts of the train as deired, being shown in the'engine44 and one ot the coaches i5 in Fig. 5.

As here shown, each of the track rails is equipped withV the devicesabove described to permit two people telephoning yfrom the ti .in at thesaine time. The return connection is eiiected by grounding one side cithe train telephones and main office telephones.

rihewires 15 as above set forth,- are connected at one end to therespective contact rail sections 17 it being understood that these wiresconnect at opposite ends to any suitable type or" switchboard ortelephone ahl in a well known manner, which is preicrably located in thetrain despatchers oiiice. Since each contact rail section has anindividual connection with the ard it follows that individualcommunication can be had by trains on different sections with theoperators in the oilice where the switchboard is located.

is shown in Fig. 3 l provide a connection to permit o' station agentsalong the railroad using the system to telephone to Athe niain oilice.As there shown the clipped end 3l of the stud 30 Vengaging the adjacentContact rail section 'has a tube 50 connected thereto into Which the endof the station telephonevvire 5l is led and to which it is.

fastened, this tube being accommodated in a slot 52 inthe tie ll.

VHaving thus described my invention what l cla-iin as ynew and desire toprotect by Letters Patent of the United States is as ol-V lows: Y

, l. A. track rail having a thickened web -orined with a longitudinalrecess, a. supplementary Yweb element covering said recess, a contactrail supported adjacent to and insulated from the track rail anddivi-ded' being indivieually connected to the respec-- tive sections ofthe contact rail, =the connections betiveen said Wires and rail sectionscomprising blocks to which the ends oic the Wires are` secured, andspring pressedstuds engagingsaid blocks. Y

l inciter 3. A. track rail having a thickened web f'ionnied with -alongitudinal recess, a supplementary web element covering said recess,

asectional Contact 'rail-supported adjacent 'to and insulated from thetrack rail, Wires*` vin said recess, blocks to which said Wires 1 areconnected at one end, studs adapted to Y bear upwardly against saidblocks and rail sections, cupped enlargements on the lower ends of saidstuds, springs *bearing vup- Y' ward-ly Vin said cupped enlargements,and

velectrical vconnection devices between the respective Vcuppedenlargements.

et, track rail having ay thickened web forined with a ylongitudinalrecess, a supplenientary web eleinenrt covering vsaid recess,

arsectiona'l contact rail supported adjacent v to ,and insulated fromthe track rail, Wires in said recess, `blocks Vto which said Wires Yareconnected at rone end, studs adapted to bear upwardly against saidblocks and rail sections, cupped enlargements on the lower ends i ofsaid studs, springs bearing iipnzaifdly in said cupped enlargements, and

electrical connection devices betiveenthe respective cuppedenlargements, said devices .comprising bars having semi-circular endsi'itting against thesaid Acupped enlargements.
